Definition

LAST MODE/LAST SETPOINT used before power down.

LAST MODE/LAST LOCAL SETPOINT on power down.

TPSC (Three-Position Step Control) OUTPUT START- UP MODE— This selection determines what position the motor will be in when powered up or in the failsafe position.

LAST OUTPUT— At power-up in automatic mode, the motor position will be the last one prior to power down. When the unit goes into FAILSAFE, it will stay in automatic mode; motor will not be driven to the configured failsafe position.

FAILSAFE OUTPUT— At power-up in manual mode, the motor will be driven to either the 0 % or 100 % output position, whichever is selected at prompt FAILSAFE. For Burnout/None, when the unit goes into FAILSAFE, it will go to manual mode; motor will be driven to the configured failsafe position.

SETPOINT HIGH LIMIT*— This selection prevents the local and remote setpoints from going above the value selected here. The setting must be equal or less than the upper range of the inputs.

SET POINT LOW LIMIT*— This selection prevents the local and remote setpoints from going below the value selected here. The setting must be equal or greater than the lower range of the inputs.

CONTROL OUTPUT DIRECTION— Select direct or reverse acting.

DIRECT ACTING CONTROL— The controller’s output increases as the process variable increases.

REVERSE ACTING CONTROL— The controller’s output decreases as the process variable increases.

*The local setpoint will automatically adjust itself to be within the setpoint limit range. For example, if SP = 1500 and the SP HiLIM is changed to 1200, the new local setpoint will be 1200.

OUT RATE

PCT/M UP

ENABLE

DISABL

0 to 9999 % per minute

OUTPUT CHANGE RATE— Enables or disables the Output Change Rate. The maximum rate is set at prompt PCT/M UP or PCT/M DN. Only available for PID-A, PID-B, PD+MR control algorithms.

ENABLE— Allows output rate.

DISABLE— Disables output rate.

OUTPUT RATE UP VALUE— This selection limits the rate at which the output can change upward. Enter a value in percent per minute. Appears only if OUT RATE is enabled. “0” means no output rate applied.

PCT/M DN

0 to 9999 % per minute

OUTPUT RATE DOWN VALUE— This selection limits the rate at which the output can change downward. Enter a value in percent per minute. Appears only if OUT RATE is enabled. “0” means no output rate.

OUTHiLIM

–5.0 to 105 % of output

HIGH OUTPUT LIMIT— This is the highest value of output beyond which you do not want the controller automatic output to exceed. Use 0 % to 100 % for digital output type. Use –5 % to 105 % for current position output.
